Application filed July 3, 1900.

To a, whom it 1 way concern:

Beit known that-I, JACQUES HOHL, a citizen of the United States, residing at No. 619 Savoye street, West Hoboken, in the county of Hudson, State of New Jersey, have invented certain new and useful Improvements in- Looms, of which the following is a specification;

This invention relates to what are known as needle-looms, and'it consists in certain new organizations of devices, hereinafter set out in detail, whereby the operation of the loom is improved and rendered more certain, v

exact, and uniform. i

The improvements are applicable to looms of various types for weaving various materials.

In the accompanying drawings, Figure l is a plan view of so much of. the-machine as is requisite to the purpose of illustrating the in-' vention; Fig. 2, an end elevation thereof; Fig. 3, a front elevation, partly in section, on the line 3 3 of Figs. land 2. Fig. at isa detail perspective view showing the devices for taking the looped weft-thread from the needle and the shuttle carrying the selvagethread andthe coactingparts; Fig. 5 a side. elevation of the parts shown in Fig. 4,- but in a different position. Figs. 6, 7, and-8 areplan views respectively illustrating the operationof taking the weft-loop'from the needle, passing the loop over the shuttle, and finally delivering the loop to be drawn down against the selvage-thread. Fig. 9 is a detail enlarged plan showing the tension device carried-by the needle.

Except as herein specified the loom may be of ordinary construction, and in the drawings it has not been considered necessary to extend the illustrations beyond the parts involved in or affected by the improvements herein claimed. I

In Figs. 1 and 2, A represents the shed; B, thefinished cloth; 0, the cloth, beam or roll upon which the cloth is wound, and D D stationary parts of theframe. The lay-frame, arranged appropriately in front of the clothbeam 0, is composedof uprights E E, respectively mounted at the'bottom upon pivots E and connected near their tops, but below the shedfby'a cross-bea'nrF, above which they LOQM.

arrangement, and which is seen in end elevation in Fig. 2 and is also indicated by the dotted line f in Fig. 1. The lay-frame is connected-by a pitman c with a crank e on a shaft 6 which receives appropriate motion properly timed,as hereinafter indicated. This construction is common or is in no way essen tial to the present invention. I On the front 60 of the lay-beam Fis mounted a beam G, having formed in it a dovetailed track or way in which fits and slides a block or carriage H,-having a laterally-projecting L-shaped bracket H, carrying a vertical post H aperneedle end, which is adjustably secured in the post by a set-screw h, the needle being thus held at an appropriate elevation-to prop- I erly pass through the shed. The general shape of the needle is seen particularly in Fig. 1, from which it appears that the needle is bent in its length so that its eye end lies parallel with and above the bar in which the needle-carrier travels, whereas its outer end is in'a plane in front of such bar.

A shaft 1, to be appropriately mounted in suitable bearings and whose axis is at right angles to the transverse plane of the machine, is located at the lower right-hand side of the machine and-has upon its inner end a disk I. pin 1 on the disk works in a curved slot in a vibrating arm K, fast upon a rock-shaft K,

rof the machineand whose axis is. parallel with that of the shaft-I. The upper end of the arm K is transversely slotted, and in this slet, by means of a clamping-bolt, is adjustably secured a rearwardly-projecting horizon- Ztal finger or plate k, which lies closely between rollers Z Z, mounted on brackets secured -;to the rocking needle-actuating arm L, which ;is pivoted at its lower end uponthe rockshaft K on an axis Z substantially parallel with that of the lay-frame, andis therefore jcapable of following or conforming to its vibratory movement. The upper end of the 'rocking arm L passes loosely through the recess or opening of the L-shaped bracket H, projecting laterally from the block traveling in the guide or way in the bar or beam G. As thelay-beam vibrates the rocking arm L, by reason of its engagement with the bracket H", follows its movement, while at the same time the cooperating or actuating relation between the arm L and the slotted arm K, driven by the disk on the shaft I, is maintained by the horizontal plate or finger It. The upper end of the rocking arm L is provided with a bearing-block Z in which is mounted a transverse pin Z on the end of a cylinder or sleeve Z Fig. 3, the opposite end of which is tapped to receive the threaded end of a bolt 1, the opposite end of which is formed with an eye or hub Z fitting over a pin projecting from the needle carrier or block H, working in the way in the beam Gr. As, therefore, the rocking arm L is vibrated the needle-carrier is reciprocated. Appropriate adjustment of the connectionsis provided by the adjustment of the finger 7c in the slot in the rocking driven arm K and by the adjustment of the connection between the upper end of the rocking arm L and the needle-carrier H, while, as before stated, the needle may be adjusted in its supportingpost H On the needle carrier or block H, inside of the connection Z, is an apertured post m, in which is adjustably mounted, by means of a setscrew, a rod m, projecting parallel, or substantially so, with the beam G and bent outwardly at its end, for a purpose hereinafter described.

While I may employ the usual weft-thread tension device mounted upon the frame of the loom, I prefer to provide in connection with it or in lieu of it a tension device on the reciprocating needle, and such device in the form in which I have constructed and practically used it is illustrated in Figs. 9 and 1. The outer straight portion of the needle is formed horizontally with an enlarged opening, at each side of which is a guide-tube 'n n, preferably arranged parallel with the axis of this part of the needle for the entrance and exit of the weft-thread 50. Within this opening are two oppositely-arranged tension devices n pivoted,preferably,at their ends adjacent to the guide-tube n, at which the weft-thread enters, and each having, as shown in the present instance, three later-. ally-projecting eyes, the eyes on one device being arranged opposite the spaces between the eyes on the other. The two opposite devices are normally drawn away from each other by springs or elastic bands a engaging them and attached to the body of the needle, and their other ends are guided in a slotted piece 02, bridging the opening in the needle. By grasping the two tension devices they may be pressed toward each other, so that the eyes of both are in line. The weft-thread 00 may be then pressed through the tube 11, through the eyes of the tension device, thence through the eye it to the eye in the point of the needle.-

When the tension devices are released, they move away from each other and the weftthread is drawn into the M -shaped condition shown in Fig. 9. I prefer to employ elastic bands in lieu of metal springs, as in the event seams of breakage the metal parts might fall from the needle and injure the fabric or yarns.

InFigs. 1 and 2 the reed is shown as just having beaten in a weft and it and the layframe are retreating. At the left-hand side of the machine a channeled shuttle-carrier 0, Figs. 1 and 4, is pivotally connected at owith the lay-beam or the beam G. The shuttle S floats or lies in the channel and is formed with side ribs 5', that extend under the overhanging sides 0 of the carrier to prevent the shuttle from being jarred out of place. In the rear of the shuttle a plate P lies loosely in the channel of the reciprocating carrier 0 and at its outer end is pivotally connected at p with a fixed part of the frame D. The plate P, turning on its pivot 19, may be lifted up, when desired, out of the channel, in which it normally lies, and the pivotal connections 0 p permit the reciprocation of the carrier 0 without disturbing the proper cooperating relation between the carrier and the non-reciprocating plate P. A spring P, applied to the plate P and attached to a stationary part of the frame, normally draws the plate against the bottom of the channel in the carrier 0. A shuttleguard S, shown in the form of a bent wire, is

attached to the plate P at a suitable point in rear of the shuttle and extends forward over the shuttle, its end resting lightly upon or in close proximityto the shuttlenear its point and preventing endwise movement of the shuttle as the carrier vibrates. Immediately in rear of the shuttle is a star-wheel Q for receiving the weft-loop from the shuttle and releasing it at the proper time. This wheel turns in or on a proper hearing at the end of the plate P and has a smaller star-wheel Q attached to its upper face. An endwise-movable bar p is mounted in posts 13 p on the plate P, and }a spring p applied to it between the posts, lnormally draws it away from the shuttle. {one end it carries'a spring latch or pawl 1J5, acting upon the star-wheel Q, and at the other has several lateral projections, teeth, or pins 13 between which normally lies one end of a lever B, pivoted on a fixed rod or bar R, projecting from the frame-bar D below the plate P. On this lever is a pivoted spring-controlled latch R which is operated upon by an arm R adjustablymounted in a block R attached to the beam G. In the shuttle-carrier O is a transverse groove or trough o to receive the needle in its advanced position, and appropriately related to this trough is the pivoted hook or looper T, that takes the loop of weft from the needle and delivers it to the shuttle. The arm of this hook is adj ustably secured upon a rock-shaft T of appropriate length turning in bearings T on the top of the beam G and having at its inner end a projecting arm 25 to be struck at the proper time by the rod or arm m on tho needle-carrier H to actuate the hook in proper relation to the needle. At any suitable point in the length of the rock-shaft T a wedge-shaped block t is IIC attached to it, which cooperates with a correspondingly-shaped block t*, which is mounted to move endwise in a bracket 75 on the beam G and is normally urged by a spring 13 into ongagement with the part If. The purposes of these devices are to assist the movement of the shaft and hook T into either of two positions and to retain it therein until positively moved into the other position, as will be presently described.

The operation is as follows, the shafts e and I being properly timed and actuated from any suitable power connections: When the needle carrying the weft-thread has traversed the shed, it enters the groove 0' in the shuttlecarrier 0, and at that time the position of the lay-frameis such that the needle occupies the relation to the shuttle exhibited in Fig. 6. The rod m on the reciprocating needle-carriage has acted against the arm 2? on the hook rock-shaft and the wedge-shaped block or Wiper t on that shaft has been thrown down, snubbing back the wedge-shaped block until it passes beneath it, when the reaction of the spring 25 further depresses the Wiper t and completes the movement of the hook, bringing it into the position shown in Fig. 6, where it passes between the upperface of the needle and the weft-thread. As the lay-frame continues to advance the needle recedes and the loop of the weft, Fig. 7, is passed over the nose of the shuttle, the lower part of the loop lying in the groove 0, insuring its passage under the shuttle, while the upper strand of the loop is directed above the shuttle by the supporting-hook, As the lay-frame continues to advance the loop is further carried over or around the shuttle until the projection V or the outer end of the hook-arm above the hook comes against a stop-arm V, projecting from the frame, when the hook is thrown back, (the operation of the parts 25 i being now repeated, but in a reverse direction.) The hook is restored to its normal position, being withdrawn from the loop, which now slips entirely past the shuttle and engages a tooth of the star-wheel Q, Fig. 8. At this time the rod R strikes the latch R on the lever B, the upper end of which is forced against one of the pins 19 the pawl 19 is moved forward to act upon the small star-wheel Q, and a partial rotation is imparted to the wheel Q in the direction of the arrow, Fig. 8, so that the weft-loop is delivered from the tooth of the wheel and is drawn down upon the selvage or shuttle thread W-by the continued retreat of the needle to its normal or initial position. The weft or filling is beaten home by the reed and the lay-frame then retreats.

For purposes of adjustment multiple pins or teeth 10 are provided, the rod R is adjustably mounted in its support, and the hook T is adjustably connected with its rock-shaft.

The construction illustrated and described has been demonstrated by practical use to be an efficient one and is the best now known to me. Obviously, however, those skilled in the and its actuating-arm.-

art may devise modifications or changes in the structure without departing from the spirit of the invention or materially changing the construction or mode of operation.
